Weird Worlds: Return To Infinite Space is one of my favourite games since that it gives players an entire galactic voyage in a handful of minutes. Every time you set out and explore the randomised galaxy, you'll encounter new planets, aliens and wacky shenanigans... all of which takes takes a quarter of an hour or less. Considering that you can pay what you want, this is a proper bargain and perfect for dipping into during your lunch hour.
